Q. Figure I and Figure II are similar figures.Figure IFigure IIWhich proportion must be true?ABRS=CDTUABTU=AFUVOption 1Option 2EFST=CDWRABWV=EFST
Identify Similar Figures: Since the figures are similar, corresponding sides are in proportion.
Match Corresponding Sides: We need to match the corresponding sides of Figure I and Figure II to set up the correct proportion.
Set Up Proportions: If RS corresponds to TU and AB corresponds to CD, then the proportion (RS)/(AB)=(TU)/(CD) should be true.
Verify Proportions: Similarly, if ST corresponds to WV and EF corresponds to AB, then the proportion EFST=CDWR should be true.
Select Correct Option: The other proportions given do not match corresponding sides correctly, so they can't be true.
Select Correct Option: The other proportions given do not match corresponding sides correctly, so they can't be true.Therefore, Option 1 is the correct proportion.
